Viscosity regulating valve

The subject invention is a valve for regulating the viscosity of fluid. The valve includes a housing defining a bore having a first inlet supplying "cold" hydraulic fluid at a first viscosity and a second inlet supplying "hot" hydraulic fluid at a second viscosity. A spool valve disposed within the bore has at least one land to proportionally control the flow of hydraulic fluid through the inlets. Hydraulic fluid from the first and second inlets mixes within the valve and exits the valve through an outlet at an optimum viscosity. A flow restrictor creates a pressure force on the spool valve that is proportional to the viscosity of the hydraulic fluid flowing through the outlet. The pressure force acts to move the spool valve such that the spool valve partially blocks the flow of hydraulic fluid through the first and second inlets, thereby controlling the proportion of "cold" and "hot" fluid to maintain the viscosity of the hydraulic fluid flowing through the outlet.

Automatic water pressure control valve balancing temperature of mixed water

The present invention discloses an automatic water pressure control valve balancing the temperature of mixed water, eliminating a cylinder enclosing the pressure control piston and multiple seal rings, to reduce the number of parts and to minimize the production costs of the automatic water pressure control valve, and a second automatic water pressure control valve simplifying the structure of the piston within the cylinder to enhance productivity of the automatic water pressure control valve, and comprising additionally the backflow cutoff valves in each of the hot water outlet and the cold water outlet to prevent back flows of water. Therefore, initial control of water pressure is easy because the piston is always placed in the center of the cylinder while water doesn't flow.

Flow balancing in gas distribution networks

Flow distribution networks that supply process gas to two or more stations in a multi-station deposition chamber. Each flow distribution network includes an inlet and flow distribution lines for carrying process gas to the stations. The flow distribution lines include a branch point downstream from the inlet and two or more branches downstream from the branch point. Each branch supplies a station. The flow distribution network also includes highly variable flow elements in each branch. Restrictive components are placed downstream from the variable control elements in each branch. These restrictive components are nominally identical and designed to shift the bulk of the pressure drop away from the variable flow components to improve flow balancing while not unduly increasing inlet pressure. In some cases, the load shifting allows the more variable flow components to operate in the unchoked flow regime.

METHOD AND APPARATUS FOR THE CONTROL OF A PROCESS FOR THE RECOVERY OF SULPHUR

... 1343474 Recovery of sulphur SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 25 May 1971 [27 May 1970] 16966/71 Heading C1A Sulphur is produced by the reaction of H 2 S with an SO 2 -containing gas which derives from the regeneration with a reducing gas (e.g. H 2 or CO) of a solid acceptor (e.g. CuO) that has become loaded with sulphur oxides by removing these from gases, e.g. waste gases. In the method, the difference between a signal F, (corresponding to the magnitude of the reducing gas stream) and a signal F 2 (corresponding to the magnitude of the stream from the regeneration) is used to set the desired composition of the gas mixture of H 2 S and SO 2 for the sulphur recovery. The difference (F 2 -F 1 ) may be used to control the rate of H 2 S fed to react with the SO 2 to form sulphur using the system shown in the Figure.

An illustrative embodiment of the invention provides a valve seat that has hot, cold and discharge water apertures. A plate, relatively rotatable with respect to the valve seat, is pressed against the valve seat surface. A cavity formed in the plate adjacent to the surface in contact has a pair of axisymmetric lobes which are asymmetric with respect to an axis that is perpendicular to the axis of symmetry, This configuration permits cold water flow first through the valve with counterclockwise motion of the plate in spite of the relative sources of hot- and cold-water through simple inversion of the plate, as appropriate.

CONTROL VALVE FOR A REVERSE OSMOSIS WATER PURIFICATION SYSTEM

An improved control valve for a reverse osmosis (RO) water purification system for supplying relatively pure water for on-demand dispensing, wherein the improved control valve positively terminates pure water production and brine outflow to a waste or drain when a pure water reservoir reaches a substantially filled condition. The control valve responds to a predetermined pressure differential between a tap or feed water inflow and produced pure water to close a pure water outflow line when the pure water reservoir reaches a substantially filled condition, thereby positively preventing further production of pure water. Shortly thereafter, the control valve closes a brine outflow line thereby positively preventing further water flow through the system until at least a predetermined volume of the reservoir-stored pure water is dispensed. When this occurs, the control valve re-opens in sequence the brine outflow and the pure water outflow lines.

Method of taking a proportional sample of flowing gas in a line

Disclosed is a method for taking a constantly proportional flowing sample of gas flowing through a line and which is part of measuring and determining the total energy flow, that is, BTUs per minute, of combustible gas flowing through a line such as a pipeline. One method includes taking a continuous sample of the gas flowing through the line which sample is a constant proportion of the gas flowing through the line, and burning the sample in equipment which supplies air to the sample in an amount which maximizes its burning temperature. The flow rate of air which produces the maximum burning temperature of the sample is a flow rate which is directly proportional to the rate of energy flow in the main pipeline. Alternately, the flow rate of air which produces a stoichiometric mixture is directly proportional to the rate of energy flow in the main pipeline. Still further, if an excess of air is flowed to the flame, the amount of excess unconsumed oxygen is also a function of the rate of energy flow in the main pipeline. One or another of these parameters is measured.
